The good thing from an economic point of view with domestic solar, is
the short innovation period, and that consumers will buy it multiple
times. So say you have a few thousand bucks for PV that almost
provides all your power needs, and people buy that, then a couple of
years later you have it for a similar price that provides all your
needs plus half again, then some of the same people will buy that,
then a couple of years later half the price, twice as good again, the
same people will buy it again, and so on. That's the financial driver
for exponential improvement. Hopefully there's a similar enabling
technological approach to help keep up with demand. eg: if we use the
same kinds of technologies to print the panels or roof tiles or what
have you, that we use for fabbing chips. Is that plausible?
